Answer 2

To perform the given arithmetic calculations, let's take them one by one:

1. 3/7 * 2/5: (3/7) * (2/5) = 6/35

2. 1 целая 1/9 * 3/10: To multiply a mixed fraction, first convert it to an improper fraction. 1 целая 1/9 = (1 * 9 + 1) / 9 = 10/9 (10/9) * (3/10) = 30/90 = 1/3

3. 7/13 * 39/56: (7/13) * (39/56) = 273/728 = 39/104

4. 4/11 я * 4 целых: To multiply a mixed fraction, first convert it to an improper fraction. 4 целых = 4 * 1 = 4 (4/11) * 4 = 16/11

5. 7/123 целых * 1/9: To multiply a mixed fraction, first convert it to an improper fraction. 7/123 целых = (7 * 123 + 0) / 123 = 861/123 (861/123) * (1/9) = 861/1107

6. 2 целых 1/2 * 1/9: To multiply a mixed fraction, first convert it to an improper fraction. 2 целых 1/2 = (2 * 2 + 1) / 2 = 5/2 (5/2) * (1/9) = 5/18

So, the results of the calculations are as follows:

1. 3/7 * 2/5 = 6/35
2. 1 целая 1/9 * 3/10 = 1/3
3. 7/13 * 39/56 = 39/104
4. 4/11 я * 4 целых = 16/11
5. 7/123 целых * 1/9 = 861/1107
6. 2 целых 1/2 * 1/9 = 5/18
